“Bring your AI to work” is here: Microsoft edition - What Multiple Account Access to Copilot means

on
Multiple Account Access to Copilot On October 1. 2025 Microsoft released a blog post explaining how employees now can use Copilot from their personal 365 plans to work on organizational data. This is of course, an extension of the already existing "Multi account" feature that was released for corporate accounts a "couple of months" ago. In other words, “bring your own Copilot” is now a real thing in Word, Excel, PowerPoint, Outlook, and OneNote on desktop and mobile, with enterprise protections intact. “Bring your AI to work” is an important topic, and banning AI altogether might not be the answer. Whether sanctioned or shadow, AI has already entered everyday knowledge work. Microsoft’s new multi‑account access offers a safer path where employees can use Copilot from their personal Microsoft 365 subscriptions on work files, while the file’s access, auditing, and compliance still flow through the work identity and tenant.

Lync 2013 and Skype Video calling

on
For true fans of true universal communications, Christmas came early this year!
Microsoft announced the availability of Lync to Skype video calling.
And this is what it is all about, the availability of this icon, the video call button:


And what comes next? A nice video (no one in the other room :P )


In this screenshot I am on a Skype client, and the other side is on a Lync 2013 klient.

This is one of the really anticipated updates, and it gives "universal communications" a real feel. With Lync to Skype federation enabled, your Lync 2013 users can now potentially reach millions of users, and have high quality conversations.

Enough promo, what does it take to make it work? Surprisingly little. If you already have the Skype IM/P-Audio federation set up, you are good to go. All it takes are up to date clients (Skype 7.0.0.100 and October Lync client CU).
If you haven't enabled Lync to Skype Federation, follow the simple steps outlined in this guide.

A note to end users: It only works on Skype for Windows desktop at the moment (no mobile devices just yet). And I discovered you have to get the latest version from this site to make it work (an update check within my original Skype client did not upgrade to this version, but it will soon, probably).

It will work on Lync 2013 Desktop client and iOS devices.

Happy video calling!
